Identifying a Chrysler 2.2 or 2.5 Engine

How to identify these engines, sure there are easier ways, but here is the hard way.

VIN decoding may not work for pre 1988 models.
Enter VIN in caps on the Dodge site, or else.

This is a video of me swapping out a slider cam in an '84 Dodge Rampage
with the 2.2L engine, for a roller cam from a '91 Spirit or Shadow or
something.
